DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS

The invention is described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein. Rather, these exemplary embodiments are provided so that this disclosure is thorough, and will fully convey the scope of the invention to those skilled in the art. In the drawings, the size and relative sizes of layers and regions may be exaggerated for clarity. Like reference numerals in the drawings denote like elements.

Prior to explaining exemplary embodiments of the present invention, for the relevant terminology may be defined for the description below. In the following description, for the purposes of explanation, numerous specific details are set for the in order to provide a through understanding of the present invention. It is apparent, however, to one skilled in the art that the present invention may be practiced without these specific details or with an equivalent arrangement. In other instances, well-known structures and devices are shown in block diagram form in order to avoid unnecessarily obscuring the present invention.

For example, an electronic appliance (e.g., a mobile terminal) may be deployed as a device, a mobile device, cellular handset (or phone), a cordless phone, a mobile transmitter, a stationary wireless transmitter, a wireless personal digital assistant (PDA), a wireless modem, or a pager. In addition, the mobile terminal may be any information and communication appliance or multimedia appliance having a touch screen or touch pad, such as a portable multimedia player (PMP), digital broadcast receiver, personal digital assistant (PDA), portable gaming console, or smart phone.

However, the present invention is not limited only to a certain mobile terminal, and may be applied to any electronic appliance having a gesture input means. For example, devices having a gesture input means may include a mobile terminal, a television set, a large format display (LFD), a digital signage (DS), and a media kiosk. A gesture input means may include a touch pad, a touch screen, a motion sensor, and a speech recognition sensor.

In some examples, an input means is capable of inputting gesture, and may be a motion sensor, a touch pad or touch screen, and a speech recognition sensor. The device having such a gesture input means, for example, can be implemented into a mobile terminal, a television set, a large format display, a digital signage, or a media kiosk.

According to exemplary embodiments of the present invention, the invention may also relate to a method and apparatus for controlling an operation of a mobile terminal having a touch screen or touch pad. For example, the method and apparatus may enable the user to unlock the mobile terminal through an input gesture and to directly invoke an application mapped to the input gesture. The input gesture may correspond to a user action of drawing a figure or a pattern applied on the touch screen or on touch pad.

According to exemplary embodiments of the present invention, an unlocking object may be provided to unlock the mobile terminal according to user settings. The unlocking object may contain information regarding one or more unlocking gestures and applications mapped to the unlocking gestures. Also, the unlocking object may be displayed as screen data on idle screen while the mobile terminal is locked. Hence, the user may readily able to identify an unlocking gesture and an application may be invoked in response to the unlocking gesture that is mapped.

According to exemplary embodiments of the present invention, the unlocking object may not be displayed while the mobile terminal is locked according to user settings. Hence, the unlocking object may be utilized as an unlocking mechanism based on a user gesture and also be utilized as a security mechanism for protecting a privacy of the user. Settings for the unlocking object and displaying thereof may be predefined (e.g., predetermined) or may be arranged by the user.

An example of the unlocking object is shown below in TABLE 1 in which exemplary gestures associated with mapped function are illustrated.

TABLE 1 Gesture Mapped function Description

Dialer Unlock and invoke dialer 0 Main menu Unlock and invoke main menu / Call log Unlock and invoke call log

Phonebook Unlock and invoke phonebook

Message Unlock and invoke message composition . . . . . . . . .

Table 1 illustrates exemplary unlocking gestures usable by the user. The user may apply one of the listed gestures to unlock the mobile terminal and may invoke an application, function or menu that may be performed by a mapping process by comparing the applied gesture with an application according to a mapping table (e.g., TABLE 1). It is noted that the mapping process performed by comparing an unlocking gesture with an application may not be limited to the TABLE 1. The mapping conditions (e.g., mapping criteria), for example, for mapping an unlocking gesture with the respective mapped application, may be changed according to user settings, for example, an edition, an addition and a deletion of the application, or downloading an application from an external server (e.g., a server of a manufacturer). In addition, the unlocking object may be transmitted to and may be received from a different mobile terminal and may be shared therebetween.

In some examples, the unlocking object may be employed by an electronic appliance such as a television set, and an unlocking gesture may be mapped with a desired broadcast channels for selecting a channel. When the user applies one of the unlocking gestures through an input gesture means, for example, a touch screen arranged to the remote controller or television set, the television set may be unlocked and may be outputting the selected program broadcast channel based on a mapping process by comparing a channel with the input gesture.

For example, for the purpose of illustrations, it is assumed that series of gestures, for example, ‘1,’ ‘2’ and ‘3’ may be mapped with the respective mapped broadcast channel identifiers, for example, ‘ch1,’ ‘ch2’ and ‘ch3’. The user may watch a broadcast program channel indicated by a channel identifier ‘ch1’ by applying the gesture ‘1’, and the user may watch the broadcast program channel indicated by the channel identifier ‘ch2’ by applying the gesture ‘2,’ and the user may watch a broadcast program channel indicated by the channel identifier ‘ch3’ by applying the gesture ‘3’. A gesture may be entered during the display unit of the television set is turned off or on, and the television set may recognize an input gesture and the user may receive a broadcast channel associated with the applied gesture regardless of the fact that the display unit is on or off.

In some examples, when the mobile terminal is locked (e.g., locking mode), the terminal may display locking information and may display an unlocking object on idle screen so that the user may intuitively recognize the locking mode. The locking information, for example, may refer to an image, a text, or an icon that can enable the user readily to identify the current locking state of the mobile terminal. The unlocking object may contain information associated with an unlocking gesture and an application mapped to the unlocking gestures. When the user enters one of the unlocking gestures, the mobile terminal may be unlocked and the application mapped to the entered gesture may be invoked and the application may be populated to the user via a display unit. The unlocking gesture and application associated with the unlocking gesture may be set by the user by way of configuration.

In some examples, an unlocking gesture may be mapped to two or more applications. For example, applying an unlocking gesture may trigger simultaneously multiple invocation processes at which two or more applications may be invoked. For example, a gesture of

illustrated in TABLE 1 may be mapped to a phonebook function and a message function, and applying the gesture of

may cause the electronic appliance (e.g., mobile terminal) an simultaneous invocation process, consequently may invoke a phonebook function and a message function at the same time. In addition, a priority for the invocation process may be needed to be set between applications if the same unlocking gesture is applied by a user.

For example, for performing a simultaneous execution of the invocation process, the screen data associated with the phonebook function may be displayed together with a message function in a format arrangement, for example, a split screen, an overlapped screen, a vertical screen or a horizontal screen by way of configuration. In addition, the phonebook function and the message function may be simultaneously executed, but the screen data associated with the higher priority function may be displayed first and the screen data associated with lower priority function may be displayed later or may be displayed as a background. The user may switch between the two functions through multitasking.

Priorities between applications mapped to the same gesture may be enumerated by a mapping table, as exemplary illustrated below in TABLE 2.

TABLE 2 Gesture Mapped function . . . . . . 1. Phonebook 2. Message

. . . . . . . . .

As illustrate in TABLE 2, the priority between the phonebook function and the message function mapped to the same gesture of

may be configured by a mapping order.

In some examples, an option indicating whether to display the unlocking object may also be set. Another option indicating whether to display all items or to display a selected item in the unlocking object may also set.

Next, a description is given of a method for controlling the operation of a mobile terminal having a touch screen through user gestures. It is noted that the present invention is not limited to the following description and hence various embodiments are possible.

FIG. 1 is a flow chart of a process for an unlocking method for an electronic appliance (e.g., a mobile terminal) capable of unlocking the terminal using an input gesture associated with an unlocking function module according to exemplary embodiments of the present invention. In FIG. 1, when the mobile terminal in idle mode and being locked, the unlocking object may be displayed on idle screen. However, the unlocking object may be not displayed according to user settings for privacy protection.

Referring to FIG. 1, the mobile terminal may wait in the idle mode (step 101). When the mobile terminal may detect an input event (step 103), the mobile terminal may check whether the input means is locked (step 105). A locking state may then be checked when an input event may be detected. The input means, for example, may be a touch screen, a touch pad, a remote controller, or a key pad. If an input event is detected through the input means, the mobile terminal may turn on the display unit and a display unit may be deployed using a display technology (e.g., liquid crystal display (LCD) technology).

If the input means is not locked, the mobile terminal may perform an operation requested by the input event (107). For example, the mobile terminal may display the idle screen or may display the initial menu.

If the input means is locked, the mobile terminal may display locking information and may display the unlocking object on idle screen to enable the user readily to identify the locking state (step 109). Here, the unlocking object may not be displayed according to user settings. A description of the locking information and the unlocking object may be provided according to TABLE 1 and TABLE 2.

The mobile terminal may check whether a touch event can be an input through the touch screen (step 111). If a touch event is determined as not an input, the mobile terminal may await an input from the user for a preset time (e.g., predetermined time or time threshold) (step 113). If no input is received from the user prior to the preset time expires, the mobile terminal may remain in idle mode with the display unit being turned off.

As in step 115, if a touch event is determined as an input, the mobile terminal may check whether the input touch event corresponds to a gesture of a given pattern (e.g., predetermined gesture). If the input touch event does not correspond to a gesture, the mobile terminal may check whether the input touch event corresponds to an unlocking request (step 117). For example, the input touch event may correspond to the amount of time and/or strength of press input (e.g., a long press input or short press input based on a time threshold for determining pressing duration and/or strength) at a given zone (e.g., predetermined touch zone) for unlocking the mobile terminal.

If the input touch event corresponding to an unlock request (e.g., a long press input for unlocking) is determined, the mobile terminal may unlock the input means and may display an initial screen or display an idle screen) (step 121). If the input touch event does not correspond to an unlocking request, the mobile terminal may perform requested operation according to the mapping process of the applied input touch event (step 119). According to the mapping process, the mobile terminal may display a popup window indicating the locking mode, or may ignore the input touch event.

If the input touch event corresponds to a gesture, in step 115, the mobile terminal may identify the input gesture, per 123, and may check whether the input gesture is specified in the unlocking object (step 125). As such, the input gesture may be compared with an unlocking gesture specified in the unlocking object, as exemplarily illustrated in TABLE 1 or TABLE 2.

If the input gesture is not specified in the unlocking object, the mobile terminal may perform an operation requested by the input gesture (step 127). For example, the mobile terminal may determine the input gesture as an error, and may issue a notice of the locking mode, and may instruct a retry request. The mobile terminal may request the user to decide whether to include a new input gesture as an unlocking gesture in the unlocking object. If the user decides to include the new input gesture as an one of gesture of the unlocking object, the mobile terminal may request the user to assign an application corresponding to the new input gesture. During the assignment process, the mobile terminal may automatically unlock the input means, and may perform a user authentication process according to user settings.

If the input gesture is specified in the unlocking object, the mobile terminal may identify the application mapped to the input gesture (step 129). The mobile terminal may then unlock the input means, may invoke the identified application, and may display a screen for the application (step 131).

Hereinabove, exemplary processes are provided for a control method in which the mobile terminal may be unlocked according to a gesture applied to the touch screen and an application mapped to the gesture may be invoked.

FIG. 2 is an exemplary view illustrating a setting screen for an unlocking object related to the electronic appliance according to exemplary embodiments of the present invention.

As shown in FIG. 2, a mobile terminal, capable of unlocking operation according to an input gesture, is provided as an example. The mobile terminal may include an input gesture module associated with a mapping table to determine whether an input gesture matches with the respective gesture of an unlocking object. And the determination may be processed using a mapper (e.g., mapping table).

In some examples, the user may setup an option for locking and unlocking of the mobile terminal using a menu. As seen in FIG. 2, for example, five types of gestures may be provided, and the user may select an application to be mapped to one of the five gestures. FIG. 2 may show that each of the gestures

,

, /,

, and

can be mapped with respect to a dialer function, a main menu, a call log function, a phonebook function, and a message function.

The user may unlock the mobile terminal by applying (e.g., executing or making) one of the five gestures, and may immediately invoke the application mapped to the applied gesture. For example, if the user makes the gesture

through a touch screen, the mobile terminal 100 may recognize the gesture

, and may unlock the input means, and may invoke the phonebook function and display of a related screen may be followed.

The gestures of the unlocking object may be changed, added, and deleted by way of configuration of the user. If not all the gestures are mapped with applications, a gesture mapped with other function may be displayed on a terminal idle screen. For example, when gestures

and

are mapped to particular applications, the unlocking object may have information with respect to the gestures

and

and applications mapped with the gestures may be displayed.

In some examples, the unlocking object 105 may further include an option for indicating whether to hide the unlocking object is necessary to protect a privacy of the user. The user may set gestures and associated applications by controlling the access to the terminal with a restriction as to display of the unlocking object in whole or in part.

When the user sets the option to “display whole,” the entire unlocking object may be displayed on terminal idle screen in locking mode. When the user sets the option to “hide,” the unlocking object 105 may not be displayed on terminal idle screen in locking mode although the mobile terminal can be unlocked by a specific gesture.

When the user sets the option to “display in part,” only selected items of the unlocking object may be displayed on terminal idle screen in locking mode. For example, the mobile terminal may also be unlocked by executing a hidden gesture and an application mapped to the hidden gesture may also be invoked.

FIG. 3 is an exemplary view illustrating display of the unlocking object when the electronic appliance device is locked according to exemplary embodiments of the present invention.

As shown in FIG. 3 an exemplary unlocking object 330 may be provided with an option of “display whole.”

The mobile terminal may remain in idle mode as the display unit is turned off. If the mobile terminal detects an input event, the mobile terminal may turn on the display unit and may display the unlocking object 330. As the unlocking object 330 may include information associated with one or more unlocking gestures and applications mapped to the respective unlocking gestures, the user may readily able to identify a desired unlocking gesture and may invoke an application to be populated or displayed.

As shown in FIG. 3, the mobile terminal 100 may further provide a lock indicator 310 at a zone for unlocking. For example, a lock-shaped icon may be used for the lock indicator 310 to inform the user of the locking state of the mobile terminal.

The user may apply a long press input on the lock indicator 310 to unlock the mobile terminal. A “long press input” may correspond to an input of “press and hold” in which input time for the long press input may require a longer than or equal to a time threshold.

In some examples, FIG. 3, FIG. 4 and FIG. 6 may be related to a mobile terminal having a full touch screen feature. However, the present invention may not be limited to a mobile terminal having a full touch screen feature, and may also be applied to all types of mobile terminals having a touch screen such as folder type, a bar type, and a slide type. The present invention may be applied to a mobile terminal having a touch pad capable of receiving and detecting an applied gesture.

FIG. 4, FIG. 5, and FIG. 6 are exemplary diagrams illustrating various input gestures and responses according to an unlocking method in response to the input gestures according to exemplary embodiments of the present invention.

As shown in FIG. 4, FIG. 5 and FIG. 6, the user may enter a gesture, while the mobile terminal is in the locking status the terminal 100 may display the unlocking object, as shown in FIG. 3.

In FIG. 4, in response to an input with an O-shaped gesture, the mobile terminal may be unlocked and an application mapped to the input O-shaped gesture may be invoked. For example, the application mapped to the O-shaped gesture may be a main menu, and then an item in the main menu may be displayed.

Referring to FIG. 4, if the mobile terminal, being in the locking state, displays the unlocking object in idle screen, the user may apply an O-shaped gesture on the touch screen. In response to detection of the O-shaped gesture, the mobile terminal may recognize the O-shaped gesture as an unlocking gesture having an application of mapping table illustrated as an example in TABLE 1, and may unlock the input means, and may invoke the main menu according to mapping the application with the O-shaped gesture. As a result, items of the main menu may be displayed.

As shown in FIG. 5, in response to a V-shaped gesture input, the mobile terminal may be unlocked and an application mapped to the input V-shaped gesture may be invoked. By way of a configuration, for example, the application mapped to the V-shaped gesture can be a dialer, and the dialer may be invoked.

Referring to FIG. 5, when the mobile terminal, in locking state, displays the unlocking object on the idle screen, the user may make a V-shaped gesture on the touch screen. In response to detection of the V-shaped gesture, the mobile terminal may recognize the V-shaped gesture as an unlocking gesture having an application mapped illustrated as an example in TABLE 1, and may unlock the input means, and may invoke the dialer mapped to the V-shaped gesture. As a result, screen data associated with the dialer may be displayed.

As shown in FIG. 6, in response to input gesture

, the mobile terminal may be unlocked and an application mapped to the input gesture

may be invoked. If an application mapped to the gesture

is a message composer, and the message composer can be invoked.

Referring to FIG. 6, when the mobile terminal in locking state displays the unlocking object on the idle screen, the user may apply a gesture

on the touch screen. In response to the gesture

, the mobile terminal may recognize the gesture

as an unlocking gesture having an application mapped as illustrated in TABLE 1 as an example, and may unlock the input means, and may invoke the message composer mapped to the gesture

. As a result, screen data related to the message composer may be displayed.

As described above in connection with FIG. 1, FIG. 2, FIG. 3, FIG. 4, FIG. 5, and FIG. 6, the user may apply a gesture (e.g., predetermined gesture) to operate to unlock the mobile terminal and directly to invoke an application or a function mapped to the applied gesture. For example, unlocking of the mobile terminal and invocation of a desired function may be performed by a single gesture. The user may use the mobile terminal in convenient way and may execute a desired function in a rapid manner.

According to exemplary embodiments of the present invention, the mobile terminal may provide the user with a hint for a gesture-making action. As shown in FIG. 3, FIG. 4, FIG. 5 and FIG. 6, the mobile terminal may represent a guideline for visual path to follow a movement of the finger or a stylus to make a gesture on the screen.

Hereinabove, in connection with FIG. 1, FIG. 2, FIG. 3, FIG. 4, FIG. 5 and FIG. 6, a description is provided with respect to a method for controlling a mobile terminal having a touch screen in response to input of a gesture, the mobile terminal may be unlocked and a function associated with corresponding gesture may be executed.
